This is an amazing premise! The atmosphere is great. The basic gameplay mechanic is fun and promising, it can have a lot of depth.
For now I lacked the way to mark the planets and for them to have more character so that with time I could get familiar in this galaxy. The dual planet was definitely the right direction, more of that please!
I would totally develop it further. If when searching I could numerically see the zoom level, the vertical and horizontal angle of the scope and stuff like I could remember, more or less, at what coordinates was which sound.
I could also see the clients giving a little bit more direction for the last wave. So as you get closer to what they like, they get a bit more specific as to what is lacking.
Best game of LD59 for me so far, great job!
